7.8 vs 8.2 - what's a little difference?

Monster earthquake: 7.8 on the Richter scale - The South Island (Fjordland) of New Zealand is now 30 cm closer to Australia.

I suppose if STFU&GBTW can't have his home in Los Angeles, he's at least still got earthquakes. And, according to this news story, the biggest one ever on record was 8.2 in ... of course ... Wellington.

Mr. HumanTeam and I saw the consequences of one of these monster quakes (from '29?) while puttering through the South Island. One half of a mountainside just shot up several meters.
